The idea
Atrial fibrillation is an irregular rhythm in which the atria quiver instead of contracting normally.
In practice
On the tracing it is irregularly irregular, with no distinct P waves and a wavy baseline; patients are at increased risk of stroke.
Where people slip
Shivering artifact can mimic it, so rule out tremor before reporting a new finding.
